To all wiz om t may concern.'

vBe it known that I, MAX SCHWARTZ, a subject of th King of Hungary, residing at Hagerstown, in the county of IVashington and State of Maryland, have invented a certain new and useful Improvement in Spring-Heel Shoes, of which the following is a full, clear, and exact description.

The object of this invention is to etlect an economy in the manufacture of wedge or spring-heel shoes, and this object is attained by a peculiar formation of the inner sole.

The invention primarily applies to shoes having out-sewed uppers in whlch the 'upper forms the welt, and it consists of an inner sole trimmed throughout'the :tore part and shank portions so as to leave room for the stitching of the upper directly to the outer sole, and having its heel portion coterminous with the heel portion of the outer sole, as I will proceed now to explain and nally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated,

Figure 1 is a side elevation, and Fig. 2 is a longitudinal section of a spring-heel shoe of the pump style. Fig. 3 is a plan view oi' the assembled inner sole and outer sole detached. Fig. 4 is a side elevationof the asf sembled inner and outer sole. Fig. 5 is a cross-section, on line A B, Fig. l.

Heretofore it has been common to make spring-heels by inserting a wedge-like tap or lift between the inner sole and the outer sole, and it has also been proposed to use a sole of heavy stockthat could be cut'out around the orepart and shank and remove this portion to be utilized as a' welt or scrapped.

In the present invention, the sole 1 is made from any preferred stock. rlhe inner sole 2 may be made of inferior stock, preferably such as will give a heel portion of greater thickness than the.sole portion, or this result may be obtained by skiving the fore part of the sole or otherwise suitably preparing it. This inner sole is cut throughout its fore part and shank 3 and 4, respectively, of a size sufliciently smaller than the corresponding portions of the outer sole to leave an extension 5 of the outer sole to receive the stitches by which the upper is secured to it, but its heel portion 6 is cutso as to be coterminous with the heel portion o the outer sole, and in order to get the desired spring-heel or wedge eiect, the edges 7 of the breast portions of the heel of the inner sole upon opposite sides of the shank are thinned out by skiving or hammering or otherwise reduced or beveled so as to run out to nothing at their junctures with the shank of the outer sole as indicated in Figs. 3 and 4. The inner sole may be cemented or otherwise secured to the outer sole and when so secured the sole is ready to receive the upper. As indicated in Fig. 5, the last 8 is undercut at 9 so that the upper 10 may be lasted down and in toward the fore part 3 of the inner sole and its shank 4, and the lower edge of said upper turned out as at l1 to take the place of a welt and to receive the stitches 12.

Of course, if desired, a separate welt may be used and stitched down over the outturned edge of the upper and indeed the part cut from the inner sole as previously described may be used as such welt.

I have shown the invention applied to a pump and having an upper 10 and a combined quarter or counter 13 made in accordance with the invention of `William J. Campbell, as set forthr in his application for patent of even date herewith; but it is to be understood that the invention is applicable to other styles of shoes, such as oxfords and sandals, both for'children and adults.

In some instances it may be desirable to cement the bottom edge 'of the upper to the so-called sole extension 5 before stitching` The various details herein shown may be changed as desired, so long as the main feature of the invention is retained, to wit, the provision of a spring-heel by means of the inner sole and the outer sole without the intervention of a separate wedge or filler.

By the construction described, a very considerable economy of leather is effected, and a good stout durable shoe may be produced.

As already stated, the invention primarily applies to shoes having out-sewed uppers, but the invention is' not limited to such shoes, but is equally applicable to shoes where the heel portion is out-turned and the shank and fore part inturned, as in making a McKay or a Goodyear welt Shoe.

What I claim is 1. A spring-heel shoe, having an outer sole, and a superposed inner sole of less width throughout its fore part und shank than the outer sole to provide for the attachment oit the upper to the outer sole outside the inner sole, and having its heel portion eoterniinous with the heel portion ot the outer sole.

2. A spring-heel shoe, having an .outer sole and a superposed attached inner sole oi" less Width throughout its :tore part and shank than the outer sole to provide for the attachment of the upper to the outer sole be yond the inner sole and having its heel portion eoterniinous with the heel portion oi'f the outer sole, the breast end of the heel portion of the inner sole upon opposite sides of the shank being thinned out or beveled toward the shank ot the outer sole.

3. A spring-heel shoe, having an outer sole, an inner sole fitted upon seid outer sole and having ai :tore port and shank oit' houder/e less dimensions than the tore part and shank ot the outer sole and :L heel of the saine dimensions as that of the heel of the outer sole and leaving an exposed edge of the outer sole about the inner sole et the tore part and shank, the breastportione ot the heel ot the inner sole upon opposite sides of its shank being beveled toward. the shank of the outer sole, and an upper outsevved to the exposed edge of the outer sole at the tore part and shank and to the edges of the outer und inner soles at the heel to thereby Produce a Wedge effect at the heel.

ln testimony whereof il have hereunto set my hand this 3rd day of December Ar. D. e5

MAX SHW'R'Z.
